data ServerReplicas Source #
Number of server instances. A wrapper over Word type, a non-negative integer
with the same size as Int. Useful for resize a connection pool.

safeServerReplicas :: Int -> Either Text ServerReplicas Source #
Safely build ServerReplicas from non-negative and non-zero Int value.
getServerReplicasInt :: ServerReplicas -> Int Source #
Get server replic count in @Int
data ResizePoolStrategy Source #
A strategy for resizing a pool
Constructors
| NeverResizePool | Never resize the pool |
| ResizePool Int | Resize the pool by using provided total maximum connections |
